Just seen this thread - so havn't read it all the replies, so this is just a reply to the topic starter.

My 1997 Auto did this to (mine does have the EDC)

Turned out it was a fault No4 Injector which is rare as hens teeth as it has the EDC wire from it.

Managed to find one, all fixed and runs better than ever.

I did have the timing and injector altered to help, but four years later in the end it really didn't want to start or go uphill.

Hi,

I had a problem with my p38, would not go any more than 20mph.
Turns out it was the connector that attaches to the wire wich leads to the......yes you got it. the fourth injector. A fecker to get to But, no problem after using a pull tie to keep the with engine running.

Cheapest fix ever.
 
im going to try this to my manual 300tdi as soon as I finish the welding. Has anyone done this that uses there car for long journeys? I drive regularly 200miles so hoping that it gives more power for overtaking and hills but hope it doesnt knacker up m engine quicker
 
I believe you can use the injector body from something like a vw tdi engine of the same age, and just get it reset with a nozzle to suit. It's just a Bosch injector, not specific to land rover.
 
They have been used for years on 8v ve pump vw diesels. Very common engine, codes 1z ahu Alh etc.

It's a needle lift sensor, they probably don't produce them anymore, but there are plenty out there.
 
Just finished the tweaks, i'm Driving from Bath to Milton Keynes and back this weekend so will be able to give it a real test and see what happens!
 
Almost finished my welding on rear crossmember and inner arches just a sill to do them ill have a fiddle with the pump cant wait
 
Just tweaked my pump slightly. Smoke screw 1 turn, Diaphragm to 1 o'clock and star wheel 90 degrees. Doesn't smoke too much but I'm not sure if it's me being paranoid but there seems to be more of a 'knock' from the engine. Is this normal?

Could anyone that has completed the mod's give some info on how there mpg's have been effected.

Would be interesting to note if there is a decent improvement in day to day driving.
 
Yep ive noticed that fuel is lasting a lot longer, however ive got an allisport intercooler, EGR blank and de-cat so couldn't comment on just the fuel pump mod alone
 
Firstly let me say what a useful topic this is and secondly I like to say that it appears that it's of no use to me even though I spent several hours yesterday following all the posts and reading various documents that those posts pointed to! :-(

Here's my problem, and my question.

I have an original 300Tdi installed in an August 1998 Defender 90 (Manual and no A/C). It's important to note that this is one of the last 300Tdi Defenders before the TD5 came out the following month.

The problem is that I seem to have a half-and-half vehicle which has more electronics than a normal Manual TDi but not as much as a TD5. So, for example I appear to have an ECU which sat under the front middle seat (it's now cable-tied to the top of the gearbox!). And, more importantly I don't have the Bosch configuration that is required for this mod :-(

If I look at wiring diagrams, Haynes Manuals etc I can't find any configuration under the bonnet that seems the same as mine. A chap who used to work for Land Rover reckons that as they were building up the TD5 production line they started adding parts to the 300Tdi that would soon be used in the TD5 but a lot of them were never utilized (this does seem strange but perhaps it's true).

Does anyone have a similar vehicle or is there anyone who could explain the weird configuration?

It might be an idea to take some pics and post them - doesn't sound like LR production though.

I suspect you have an ES auto. These were fly by wire, they apparently had an extra 5bhp to compensate for the borg Warner box. Don't know if you can fiddle about with these.

Leave well alone in opinion.

Oops I retract most of that as I realise you require talking about a 'fender.

But yes it looks like it is a fly by wire in that too.

He said he has a Defender, so it's not going to be a std EDC car.

I don't believe there was ever a std EDC TDi 300 Defender. EDC was brought in on Discovery TDi 300 to boost power (111 to 122bhp) on autobox-only models.
